1.6 EXTERNAL CONNECTIONS
This section of the manual explains the external connection of the product.
1.6.1 Scale Base with Connector
Ohaus bases with a connector can be attached to the external load cell connector (Figure 1-1, item 12). To make the connection, plug the base connector onto the external load cell connector. Then rotate the base connector’s locking ring clockwise. Refer to section 1.7.2 for bases without a connector.
1.6.2 RS232 interface Cable to TD52P
Connect the optional RS232 cable to the RS232 connector (Figure 1-1, item 11).

1.6.3 AC Power to TD52P
Connect the AC power cord (supplied) to the power receptacle (Figure 1-1, item 10), then connect the AC plug to an electrical outlet.
1.6.4 AC Power to TD52XW
Connect the AC plug to a properly grounded electrical outlet.
1.6.5 Battery Power
The indicator can be operated on a rechargeable battery pack (not supplied) when AC power is not available. It will automatically switch to battery operation if there is power
failure or the power cord is removed. The indicator can operate for up to 21 hours on battery power. During battery operation, the battery charge symbol indicates the battery status. The indicator will automatically turn-off when the batteries are fully discharged. Find detailed installation information in battery pack (P/N 30424405) operation manual.
1.7 Internal Connections
Some connections require the housing to be opened.
1.7.1 Opening the Housing
CAUTION: ELECTRICAL SHOCK HAZARD. REMOVE ALL POWER CONNECTIONS TO THE INDICATOR BEFORE SERVICING OR MAKING INTERNAL CONNECTIONS. THE HOUSING SHOULD ONLY BE OPENED BY AUTHORIZED AND QUALIFIED PERSONNEL, SUCH AS AN ELECTRICAL TECHNICIAN.
TD52P
Remove the four Phillips head screws from the rear housing.
Remove the front housing being careful not to disturb the internal connections.
Once all connections are made, reattach the front housing.
Ohaus Corporation www.ohaus.com |
7 |
Defender 5000 Indicators Service Manual |
TD52XW
Remove the four hex head screws from the rear housing. Open the housing by carefully pulling the front housing forward. Once all connections are made, reattach the front housing.
The screws should be tightened to 2.5 N•m (20-25 in-lb) torque to ensure a watertight seal.
1.7.2 Scale Base Without Connector
For connecting bases (which do not have the connector) to a TD52P or TD52XW, a cable gland kit (P/N 30379716) is available as an accessory.
Removing the pre-installed Load Cell connector and wiring harness
Before doing the connections, remove the pre-installed Load Cell connector and wiring harness by following the steps below.
1.Open the housing by carefully pulling the front housing forward.
2.Unplug the white load cell connector from the main PCBA board (red circle).
3.Remove the metal terminal (Figure 1-1, item 12) connector from the rear housing.(green circle)
Installing Cables and Connectors
In order to meet certain electrical noise emission limits and to protect the TD52P and TD52XW from external influences, it is necessary to install a ferrite core on the load cell cable connected to the terminal. The ferrite core is included with the terminal.
To install the ferrite, simply route the cable through the center of the core and then take one wrap around the outside of the core and route the cable through the center again. Either the complete cable or the individual wires can be wrapped through the ferrite. This should be done as close to the enclosure as possible. See Figure 1-5.
Figure 1-5
Main Board Wiring Connections
Once the TD52P and TD52XW enclosure is open, connections can be made to the terminal strips on the main board, as shown in Figure 1-6.
Ohaus Corporation www.ohaus.com |

Defender 5000 Indicators Service Manual |
Figure 1-6
Jumper Connections
The TD52P and TD52XW terminals are designed to support both 2mV/V and 3mV/V load cells from the same circuitry. A load cell output rating selection jumper is not required.
Figure 1-7 shows the terminal definitions for the analog load cell terminal strip. Note that when using fourwire load cells, jumpers must be placed between the +Excitation and +Sense terminals and between the Excitation and Sense terminals.
Figure 1-7 Jumper Connections
After wiring is completed, replace the indicator housing screws. Make sure the liquid-tight connector is properly tightened.

1.7.3 RS232 Interface Cable to TD52XW
Pass the optional RS232 cable through the strain relief (Figure 1-2, item 10) and attach it to terminal block J5 (Figure 1-3, item 7). Tighten the strain relief to maintain a watertight seal.
1.7.4 MICRO SD Card Installation
The SD memory card can be used for additional storage in the Checkweighing and Counting applications. Figure 1-8 shows the installation of an SD card into the socket on the edge of the TD52P andTD52XW main board.
Figure 1-8 Sliding an SD Card into the SD Socket (left); SD Card Installed (right)
1.8 TD52XW Rear Housing Orientation
The TD52XW is delivered in the wall mount orientation with the connections exiting below the display. The rear housing may be reversed so the connections exit above the display when the TD52XW is placed horizontally on a bench. To reverse the rear housing, remove the four Phillips head screws, carefully rotate the housing 180°, and reinstall the screws.

1.9 Mounting Bracket
Attach the bracket to a wall or table using fasteners (not supplied) that are appropriate for the type of mounting surface. The bracket will accommodate up to 6 mm (1/4”) diameter screws. Locate the mounting holes as shown in Figure 1-11.
